NiagaraST

The Niagara project
is a joint effort between the University of Wisconsin-Madison and
Portland State University to study mechanisms for effectively
querying the Internet.
At PSU, we are studying queries over data
streams and XML data streams in particular.
We have developed NiagaraST, a data stream management system
based on the
Niagara 1.0 code base from the University of Wisconsin-Madison.
NiagaraST uses a novel approach for processing window queries that
significantly reduces the amount of buffering required for such queries
and which allows processing of disordered data.
In addition, we have developed
NEXMark, a benchmark for data stream queries
and implemented XMLB, a fantasy baseball demo,
showcasing our ideas for stream processing.
